EQUIPMENT FOR MANUFACTURING PLASTIC- MADE HOLLOW OBJECT FROM PERFORM AND ON EQUIPMENT, TILTING DEVICE FOR PERFORM IS MOUNTED

摘要

PURPOSE: To reduce not only production cost but also use cost by the simple arrangement of a machine structure by winding a spiral cylindrical part formed from a cam-shaped part around a column having the track of the rotary shaft of a support as an axis. CONSTITUTION: A heat conditioning chamber has the endless conveyor 9 supported by two terminal wheels 10 and furnaces 3 are dispersed along the straight line part of the conveyor. The support 11 is provided by rotationally mounting an elongated main body 12 on an arm or support element 14 through a horizontal shaft 13. The support means cooperating with the elongated cam- shaped guide part extending along the track of the support during the movement of the support 11 carried by a movable mechanism (a plate 2 or the endless conveyor 9) to be capable of sliding is mounted on the support. The cam-shaped part of a spirally wound metal rod 17 is wound around the track E of the rotary shaft 13 of the support 11 by a fine male mold. A preform 16 almost makes one revolution and the taking in and out of the preform is performed in the vicinity of the wheel 10 provided at a left-side position.
